Answer: Option C) the parental DNA splits and free nucleotides bond to their complements, building two DNA molecules from one.
Explanation:
In semi-conservative DNA replication,
- a parent double-stranded DNA splits in two.
- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate replication of a newly synthesized strand
- the new strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, option C perfectly describes semi-conservative replication of dna
The forces which acts on the vase before the fall include:
- Force exerted by the table.
<h3>What is Force?</h3>
This is described as an influence which changes the motion of an object. The force exerted before motion is that which is exerted by the table , drag and force of gravity.
During fall, all other forces act except that exerted by the table thereby making it the most appropriate choice.

Answer: d. A bar graph indicating average high and low temperatures for Amanda’s area in the autumn, winter, spring, and summer.
A scientific study requires the use of variables, on the basis of which the outcome of the study can be obtained. An independent variable refers to a variable which can be changed or manipulated in an experiment, such changes will affect the dependent variables. Dependent variables is the outcome of the research, it cannot be changed manually instead the changes occur are because of the changes in the independent variable.
In the given situation, a bar graph indicating average high and low temperatures for Amanda’s area in the autumn, winter, spring, and summer would be an effective scientific model to be incorporated in the Amanda project. This is because of the fact that both independent and dependent variables can be analyzed by this way. The temperature is an independent variable, which changes with respect to the climatic conditions, which represent a particular season like autumn, winter, spring and summer which is a dependent variable.
B and E are the right answers. If this question is not multiple choice, I think E is the best answer.
